  Abstract: Purpose of Review Despite the widespread utilization of 5-alpha reductase inhibitors (5-ARIs) for managing benign prostatic hyperplasia (BPH), certain BPH patients exhibit unresponsiveness to 5-ARIs therapy. This paper provides a comprehensive overview of the current perspectives on the mechanisms of 5-ARIs resistance in BPH patients and integrates potential biomarkers and underlying therapeutic options for 5-ARIs resistance. These findings may facilitate the development of novel or optimize more effective treatment options, and promote personalized medicine for BPH. Recent Findings The pathways contributing to resistance against 5-ARIs in certain BPH patients encompass epigenetic modifications, shifts in hormone levels, autophagic processes, and variations in androgen receptor structures, and these pathways may ultimately be attributed to inflammation. Promisingly, novel biomarkers, including intravesical prostatic protrusion, inflammatory factors, and single nucleotide polymorphisms, may offer predictive insights into the responsiveness to 5-ARIs therapy, empowering physicians to fine-tune treatment strategies. Additionally, on the horizon, GV1001 and mTOR inhibitors have emerged as potential alternative therapeutic modalities for addressing BPH in the future. Summary After extensive investigation into BPH’s pathological processes and molecular landscape, it is now recognized that diverse pathophysiological mechanisms may contribute to different BPH subtypes among individuals. This insight necessitates the adoption of personalized treatment strategies, moving beyond the prevailing one-size-fits-all paradigm centered around 5-ARIs. The imperative for early identification of individuals prone to treatment resistance will drive physicians to proactively stratify risk and adapt treatment tactics in future practice. This personalized medicine approach marks a progression from the current standard treatment model, emerging as the future trajectory in BPH management.

  Abstract: Purpose of Review Benign prostatic hyperplasia (BPH) is a disease of the lower urinary tract which often requires surgical treatment. Recently, there has been a deluge of new treatment options, rarely validated or compared to current treatments on a benchtop model. The purpose of this review is to examine the literature and report which benchtop models are currently being used, which therapies have been tested on them, and what outcomes are being studied on each model. Recent Findings There are various benchtop models to choose from, each with their unique benefits and drawbacks. Perfused porcine kidney models are used to assess bleeding on the benchtop, ex-vivo human prostate helps to see specific interactions of devices with the prostatic tissue, and all other models have evaluated tissue ablation rates and depth of coagulation. There are currently no synthetic or non-animal tissues being used for this purpose, and surgical techniques such as enucleation, water-jet ablation, prostate stents, and water vapor thermal therapy have no representation in these benchtop tests. Summary Benchtop testing serves an important role in the evaluation and comparison of surgical treatments for BPH. This testing allows these therapies to be objectively compared to one another, helping novel medical devices in their path to market and urologists make treatment decisions. Future directions may include further validation of the animal models currently being used and development of synthetic models which mimic the prostate on the benchtop.

  Abstract: Purpose of Review In this study, we describe a rare case of a male with a duplex renal collecting system with ectopic ureter insertion into the prostate who presented with sepsis and required urgent laparoscopic radical nephrectomy. This study offers urologists and emergency care practitioners a great overview of the variety of manifestations, anatomic differences, and therapeutic approaches for similar patients. Recent Findings modified reconstructive strategy could be a method of choice when addressing particular anatomies, such as incomplete duplex kidneys with ureteropelvic junction obstruction in both upper and lower poles when the obstruction is close to the confluence of the two ureters. Summary There is a spectrum of acute presentations and management strategies in adult patients with duplex collecting systems. The majority of patients presenting with obstruction and infection are managed surgically with hemi-nephrectomy; stable patients who present with less extensive anomalies were managed conservatively or with ureteral dilatation or deroofing.

  Abstract: Purpose of Review Prostate Imaging Reporting and Data System (PI-RADS) category 3 lesions present a clinical dilemma due to their uncertain nature, which complicates the development of a definitive management strategy. These lesions have an incidence rate of approximately 22–32%, with clinically significant prostate cancer (csPCa) accounting for about 10–30%. Therefore, a thorough evaluation is warranted. Recent Findings This review highlights the need for radiology peer review, including the confirmation of dynamic contrast-enhanced (DCE) compliance, as the initial step. Additional MRI models such as VERDICT or Tofts need to be verified. Current evidence shows that imaging and clinical indicators can be used for risk stratification of PI-RADS 3 lesions. For low-risk lesions, a safety net monitoring approach involving annual repeat MRI can be employed. In contrast, lesions deemed potentially risky based on prostate-specific antigen density (PSAD), 68 Ga-PSMA PET/CT, MPS, Proclarix, or AI/machine learning models should undergo biopsy. It is recommended to establish a multidisciplinary team that takes into account factors such as age, PSAD, prostate, and lesion size, as well as previous biopsy pathological findings. Summary Combining expert opinions, clinical-imaging indicators, and emerging methods will contribute to the development of management strategies for PI-RADS 3 lesions.

  Abstract: Purpose of Review Management of urotrauma is a crucial part of a urologist’s knowledge and training. We therefore sought to understand the state of urotrauma education in the United States. Recent Findings Using themes of “Urotrauma” and “Education,” we performed a systematic review and meta-analysis by searching for studies in MEDLINE, all Cochrane libraries, EMBASE, BIOSIS, Scopus, and Web of Science through May 2023. The primary outcome was the pooled rate of urology trainee and program director attitudes toward urotrauma education. Secondary outcomes involved a descriptive summary of existing urotrauma curricula and an assessment of factors affecting urotrauma exposure. Of 12,230 unique records, 11 studies met the final eligibility criteria, and we included 2 in the meta-analysis. The majority of trainees and program directors reported having level 1 trauma center rotations (range 88–89%) and considered urotrauma exposure as an important aspect of residency education (83%, 95% CI 76–88%). Despite possible increases in trainee exposure to Society of Genitourinary Reconstructive Surgeons (GURS) faculty over the preceding decade, nearly a third of trainees and program directors currently felt there remained inadequate exposure to urotrauma during training (32%, 95% CI 19–46%). Factors affecting urotrauma education include the limited exposure to GURS-trained faculty and clinical factors such as case infrequency and non-operative trauma management. Summary Urology resident exposure to urotrauma is inadequate in many training programs, underscoring the potential value of developing a standardized curriculum to improve urotrauma education for trainees. Further investigation is needed to characterize this issue and to understand how it impacts trainee practice readiness.

  Abstract: Purpose of Review Asymptomatic bacteriuria (ASB) can be found in the general population but it is more common in catheterized patients. Some patients develop urinary tract infections (UTI) and others stay asymptomatic throughout time. The scientific community lacks a pathophysiologic explanation of why asymptomatic bacteriuria stays asymptomatic most of the time, and why and how it sometimes transitions to UTI. In an attempt to bridge this gap in knowledge, a summary of the current literature is conducted on the pathophysiologic differences between ASB and UTI, beyond their clinical differences. Recent Findings ASB and UTI cannot be differentiated just by their phylogroup or number of virulence factors. The difference may be in their metabolism gene expression. Summary The literature lacks a pathophysiological explanation of the transition from ASB to UTI, and recent discoveries suggest that metabolic gene expression may hold the key.

  Abstract: Purpose of Review Our understanding of patterns of prostate cancer recurrence after primary treatment of localized disease has significantly evolved since the development of positron emission tomography (PET) agents targeting prostate cancer. Previously, most biochemical recurrences were not associated with imaging correlates when restaging with computed tomography (CT), magnetic resonance imaging (MRI), or bone scintigraphy and, hence, were typically assumed to represent occult metastases. A rising prostate specific antigen (PSA) after previous local therapy prompting a PET scan showing uptake limited to regional lymph nodes is an increasingly common clinical scenario as advanced prostate cancer imaging becomes more widely utilized. The optimal management strategy for patients who have lymph node recurrent prostate cancer is both unclear and evolving, particularly in terms of local and regionally directed therapies. Stereotactic body radiation therapy (SBRT) utilizes ablative radiation doses with steep gradients to achieve local tumor control while sparing nearby normal tissues. SBRT is an attractive therapeutic modality due to its efficacy, favorable toxicity profile, and flexibility to administer elective doses to areas of potential occult involvement. The purpose of this review is to briefly describe how SBRT is being implemented in the era of PSMA PET for the management of solely lymph node recurrent prostate cancer. Recent Findings SBRT has been shown to effectively control individual lymph node tumor deposits within the pelvis and retroperitoneum for prostate cancer and is well-tolerated with a favorable toxicity profile. However, a major limitation thus far has been the lack of prospective trials supporting the use of SBRT for oligometastatic nodal recurrent prostate cancer. As further trials are conducted, its exact role in the treatment paradigm of recurrent prostate cancer will be better established. Although PET-guided SBRT appears feasible and potentially beneficial, there is still considerable uncertainty about the use of elective nodal radiotherapy (ENRT) in patients with nodal recurrent oligometastatic prostate cancer. Summary PSMA PET has undoubtedly advanced imaging of recurrent prostate cancer, revealing anatomic correlates for disease recurrence that previously went undetected. At the same time, SBRT continues to be explored in prostate cancer with feasibility, a favorable risk profile, and satisfactory oncologic outcomes. However, much of the existing literature comes from the pre-PSMA PET era and integration of this novel imaging approach has led to greater focus on new and ongoing clinical trials to rigorously evaluate this approach and compare to other established treatment modalities utilized for oligometastatic, nodal recurrence of prostate cancer.

  Abstract: Purpose of Review Prostate ablation is increasingly being utilized for the management of localized prostate cancer. There are several energy modalities with varying mechanism of actions which are currently used for prostate ablation. Prostate ablations, whether focal or whole gland, are performed under ultrasound and/or MRI guidance for appropriate treatment plan execution and monitoring. A familiarity with different intraoperative imaging findings and expected tissue response to these ablative modalities is paramount. In this review, we discuss the intraoperative, early, and delayed imaging findings in prostate from the effects of prostate ablation. Recent Findings The monitoring of ablation both during and after the therapy became increasingly important due to the precise targeting of the target tissue. Recent findings suggest that real-time imaging techniques such as MRI or ultrasound can provide anatomical and functional information, allowing for precise ablation of the targeted tissue and increasing the effectiveness and precision of prostate cancer treatment. While intraprocedural imaging findings are variable, the follow-up imaging demonstrates similar findings across various energy modalities. Summary MRI and ultrasound are two of the frequently used imaging techniques for intraoperative monitoring and temperature mapping of important surrounding structures. Follow-up imaging can provide valuable information about ablated tissue, including the success of the ablation, presence of residual cancer or recurrence after the ablation. It is critical and helpful to understand the imaging findings during the procedure and at different follow-up time periods to evaluate the procedure and its outcome.

  Abstract: Purpose of Review Metastatic prostate cancer remains universally lethal. Although de-novo metastatic prostate cancer was historically managed with systemic therapy alone, local therapies are increasingly utilized in the early treatment of the disease, particularly in patients with oligometastatic prostate cancer (OMPC). OMPC represents an intermediate stage between clinically localized and widespread metastatic disease. Diseases classified within this stage present an opportunity for localized targeting of the disease prior to progression to widespread metastases. The purpose of this review is to discuss the contemporary and emerging local therapies for the treatment of OMPC. Recent Findings To date, there are three utilized forms of local therapy for OMPC: cryoablation, radiation therapy, and cytoreductive prostatectomy. Cryoablation can be utilized for the total ablation of the prostate and has shown promising results in patients with OMPC either in combination with ADT or with ADT and systemic chemotherapy. Radiation therapy along with ADT has demonstrated improvement in progression-free survival. The STAMPEDE Arm G, PEACE-1, and the HORRAD clinical trials have investigated radiation therapy for mPCa compared to standard of care versus systemic therapy with varying results. Cytoreductive radical prostatectomy (CRP) in conjunction with ADT has also been proposed in the management of OPMC with promising results from case–control and retrospective studies. Currently there are larger controlled trials investigating CRP for OPMC including the SIMCAP, LoMP, TRoMbone, SWOG 1802, IP2-ATLANTA, g-RAMPP, and FUSCC-OMPCa trials. Summary Given the novel nature of local treatments for OPMC, treatment selection is still controversial and requires long-term follow-up and randomized clinical trials to aid patient and clinician decision making.

  Abstract: Purpose of Review Stress urinary incontinence after prostatectomy is a common and debilitating side effect. Immediate post-prostatectomy management emphasizes pelvic floor muscle exercises. Per American Urologic Association guidelines, if incontinence persists for more than 12 months postoperatively, surgical interventions are the mainstay of treatment. Treatment decisions depend on a multitude of factors. The goal of this paper is to review recent literature updates regarding the diagnosis of male SUI to better guide surgical treatment decision-making. Recent Findings Patient history is a critical component in guiding surgical decision making with severity and bother being primary factors driving treatment decisions. Recent studies indicate that a history of pelvic radiation continues to impact the overall duration and complication rate associated with artificial urinary sphincters (AUS). Cystoscopy should be done on every patient preparing to undergo surgical SUI treatment. Urodynamics and standing cough stress tests are additional diagnostic testing options; these tests may augment the diagnosis of SUI and better delineate which patients may benefit from a male sling versus AUS. Summary Treatment of SUI after prostatectomy can improve health-related quality of life. A patient history focused on severity and degree of bother in addition to the use of ancillary office testing can help guide surgical treatment decisions to optimize patient continence goals.

  Abstract: Purpose of Review The purpose of this review is to highlight literature regarding resident boot camps published across surgical specialties with a focus on urology. Herein, we discuss different boot camp iterations, their results, and the integration of simulation into their curriculum. We review program elements such as curriculum, course length, and efficacy as well as areas for continued investigation. Recent Findings The field of urology has grown in both the breadth of knowledge and the complexity of procedures. With urology now being an integrated surgical subspecialty, interns often start on the urology service despite limited experience navigating this unique specialty. The boot camp model is one method by which interns and junior residents participate in consolidated training programs to best prepare them for a patient-facing role and the day-to-day demands of residency. Urology programs, both in the USA and abroad, have begun integrating boot camps into their training programs with positive results. Summary Urology boot camps can be a valuable part of training programs for interns to quickly establish medical knowledge, skills, and efficiency. Boot camps should be easily accessible, have sufficient support from institutions, and provide effective training through various methods such as didactics and simulation.

  Abstract: Purpose of Review Surgical simulation has become a cornerstone for the training of surgical residents, especially for urology residents. Urology as a specialty bolsters a diverse range of procedures requiring a variety of technical skills ranging from open and robotic surgery to endoscopic procedures. While hands-on supervised training on patients still remains the foundation of residency training and education, it may not be sufficient to achieve proficiency for graduation even if case minimums are achieved. It has been well-established that simulation-based education (SBE) can supplement residency training and achieve the required proficiency benchmarks. Recent Findings Low-fidelity modules, such as benchtop suture kits or laparoscopic boxes, can establish a strong basic skills foundation. Eventually, residents progress to high-fidelity models to refine application of technical skills and improve operative performance. Human cadavers and animal models remain the gold standard for procedural SBE. Recently, given the well-recognized financial and ethical costs associated with cadaveric and animal models, residency programs have shifted their investments toward virtual and more immersive simulations. Summary Urology as a field has pushed the boundaries of SBE and has reached a level where unexplored modalities, e.g., 3D printing, augmented reality, and polymer casting, are widely utilized for surgical training as well as preparation for challenging cases at both the residents, attending and team training level.

  Abstract: Purpose of Review Artificial intelligence (AI) chatbots have emerged as a potential tool to transform urology by improving patient care and physician efficiency. With an emphasis on their potential advantages and drawbacks, this literature review offers a thorough assessment of the state of AI-driven chatbots in urology today. Recent Findings The capacity of AI-driven chatbots in urology to give patients individualized and timely medical advice is one of its key advantages. Chatbots can help patients prioritize their symptoms and give advice on the best course of treatment. By automating administrative duties and offering clinical decision support, chatbots can also help healthcare providers. Before chatbots are widely used in urology, there are a few issues that need to be resolved. The precision of chatbot diagnoses and recommendations might be impacted by technical constraints like system errors and flaws. Additionally, issues regarding the security and privacy of patient data must be resolved, and chatbots must adhere to all applicable laws. Important issues that must be addressed include accuracy and dependability because any mistakes or inaccuracies could seriously harm patients. The final obstacle is resistance from patients and healthcare professionals who are hesitant to use new technology or who value in-person encounters. Summary AI-driven chatbots have the potential to significantly improve urology care and efficiency. However, it is essential to thoroughly test and ensure the accuracy of chatbots, address privacy and security concerns, and design user-friendly chatbots that can integrate into existing workflows. By exploring various scenarios and examining the current literature, this review provides an analysis of the prospects and limitations of implementing chatbots in urology.

  Abstract: Purpose of Review The history of multiple weight loss medications has been a concerning paradox based on an increased cardiovascular risk despite significant reductions in adipose tissue and weight. A new class of weight loss medications could change this past narrative based on early preliminary results of cardiovascular risk (not events—still need to be determined) and weight reduction in non-diabetics that acutely competes with results achieved with bariatric surgery. The purpose of this review is to provide a comprehensive summary of the advantages and disadvantages of these newer medications, and how they could impact urology. Recent Findings Weight loss of − 15 to − 20% compared to baseline has become plausible in the short-term and preliminary guidance to reduce acute and chronic adverse events are receiving attention. However, the cost, access, conflicts of interest, supply chain, life-long adherence issues, and the long-term diverse implications on mental and physical health when exposed to this class of medications (GLP-1 agonists) are unknown. The profound caloric reductions should also result in baseline or ongoing nutritional deficiency testing, and general and specific dietary recommendations, which could theoretically mimic some bariatric surgery pre- and post-surgical protocols but has yet to be studied. Regardless, the potential impact of these medicines within a variety of medical specialties needs clinical research. Summary Current and future lifestyle interventions, dietary patterns, and medicines in the weight loss category need to be held to a paradigm whereby cardiovascular health should improve with significant weight loss without a negative impact on mental health. In urology, the ability to impact cancer risk, ED, FSD, incontinence, infertility, nephrolithiasis, and multiple other endpoints are plausible (based on bariatric surgery data) but need preliminary clinical research. Other medicines with a similar or even larger potential impact are in clinical trials, and thus, a concise overview for clinicians and researchers was needed for objective guidance. Currently, comprehensive lifestyle changes utilized with and without these medications continue to garner positive mental, physical, and legacy effects, which suggest that they are as necessary as ever in the treatment of the numerous conditions impacted by unhealthy weight gain.

  Abstract: Purpose of Review To summarise the literature on laser safety during endourological practice. Recent Findings Holmium and Thulium Fiber laser are the two main energy sources in the current clinical practice. The latter may have superior properties, but more clinical studies are needed to formally establish this. Laser injury to urothelium is more dependent on user experience rather than laser type. Smaller laser fibres allow for lower intra-renal temperature profiles. Operators should pay close attention to laser technique including maintaining the safety distance concept and only firing the laser when tip is clearly in view. When adjusting laser settings, pay close attention to resultant power given the associated heat changes. Prolonged periods of laser activation are to be avoided for the same reason. Outflow can be manipulated such as with access sheath to mitigate temperature and pressure changes. There is still limited evidence to support the mandate for compulsory use of eye protection wear during laser lithotripsy. Summary Lasers are the gold standard energy source for stone lithotripsy. However, the safe clinical application of this technology requires an understanding of core principles as well as awareness of the safety and technical aspects that can help in protecting patient, surgeon and operating staff.

  Abstract: Purpose of Review Many prostate cancer active surveillance protocols mandate serial monitoring at defined intervals, including but certainly not limited to serum PSA (often every 6 months), clinic visits, prostate multiparametric MRI, and repeat prostate biopsies. The purpose of this article is to evaluate whether current protocols result in excessive testing of patients on active surveillance. Recent Findings Multiple studies have been published in the past several years evaluating the utility of multiparametric MRI, serum biomarkers, and serial prostate biopsy for men on active surveillance. While MRI and serum biomarkers have promise with risk stratification, no studies have demonstrated that periodic prostate biopsy can be safely omitted in active surveillance. Summary Active surveillance for prostate cancer is too active for some men with seemingly low-risk cancer. The use of multiple prostate MRIs or additional biomarkers do not always add to the prediction of higher-grade disease on surveillance biopsy.

  Abstract: Purpose of Review Prostatic artery embolization (PAE) is an emerging minimally invasive technique for lower urinary tract symptom reduction from benign prostatic hypertrophy (BPH). While the technique is becoming increasingly popular with patients and interventional radiologists, most urologists remain skeptical of the PAE’s long-term efficacy and comparative success to the gold standard transurethral resection of the prostate. Recent Findings PAE has been found in multiple meta-analyses to perform similarly to the gold standard transurethral resection of the prostate (TURP) with regard to patient-driven measures like IPSS and IPSS-QoL, while also performing favorably in objective measurements including Qmax and PVR out to at least 12 months post intervention. Furthermore, PAE has a demonstrated shorter hospital length of stay and fewer adverse events when compared to TURP. Summary PAE provides patients with an alternative to transurethral options for the management of LUTS in the setting of bladder outlet obstruction. While long-term evidence demonstrating the durability of PAE is still forthcoming, the procedure has been demonstrated to be safe according to multiple meta-analyses. Patients deserve to be counseled on PAE as an alternative to surgery and made aware that while the overall treatment effect may not be as robust or durable, the procedure carries a favorable adverse event profile that is attractive to patients wishing to avoid a trans-urethral approach.
